Unique visitors are the individuals who visit your sites at least once in a fixed time frame based on the IP address information found in the log files.

The initial session by a user during any given date range is considered to be an additional visit and an additional visitor. Any future sessions from the same user during the selected time period are counted as additional visits, but not as additional visitors. Visitors is a metric that attempts to count unique 'people' visiting your site

Unique Visitors are those who visit your site at some specific time range with the same IP address.
Visitors are the total number you get. This may include some revisitors in the time of the same IP adress.
